Prerequisites

• Python 3.13 or higher
• Azure CLI installed and configured
• Azure subscription and appropriate permissions
• Service Principal with required access

Installation

1. Clone the repository:

git clone <repository-url>
cd py-az-mcp

2. Install dependencies using uv:

uv pip install -r requirements.txt

Configuration

1. Create a Service Principal and configure environment variables by running the utility script:

python create_service_principal.py

This script will:

• Authenticate you with Azure interactively
• Create a new Service Principal with Contributor role
• Automatically generate a .env file with the required credentials:
  • AZURE_CLIENT_ID
  • AZURE_CLIENT_SECRET
  • AZURE_TENANT_ID
  • AZURE_SUBSCRIPTION_ID

Note: The .env file is automatically excluded from git tracking for security purposes.

Claude Desktop Configuration

To use this MCP server with Claude Desktop, configure the following:

1. Create or update the Claude Desktop configuration file:

{
  "mcpServers": {
    "Azure": {
      "command": "uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "mcp",
        "run",
        "/your-path-to/py-az-mcp/server-azure.py"
      ]
    }
  }
}

The configuration file is located at:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Replace YOUR_USERNAME with your actual system username in both paths.

3. Ensure your virtual environment is properly set up:

cd /Users/YOUR_USERNAME/Source/Code/py-az-mcp
python -m venv .venv
source .venv/bin/activate
pip install mcp[cli]

4. Verify the configuration:
   • Open Claude Desktop
   • Click on the settings icon (⚙️)
   • Navigate to the "MCP Servers" section
   • The Azure server should be listed and enabled

Note: The server will start automatically when needed by Claude Desktop. Ensure all environment variables from the .env file are properly configured before using Azure commands through Claude.

Usage

1. Start the MCP server:

uv run --with mcp[cli] mcp run server-azure.py

2. The server will be available at http://127.0.0.1:6274

Example API Calls

List all subscriptions:

curl -X POST http://127.0.0.1:6274/tool/azure-cli -H "Content-Type: application/json" -d '{"command": "account list --output json"}'

List all resource groups:

curl -X POST http://127.0.0.1:6274/tool/azure-cli -H "Content-Type: application/json" -d '{"command": "group list --output json"}'

Project Structure

• server-azure.py: Main MCP server implementation with Azure CLI integration
• create_service_principal.py: Utility script for creating Azure Service Principal
• pyproject.toml: Project dependencies and configuration
• .env: Environment variables configuration (not tracked in git)

Error Handling

The server includes comprehensive error handling:

• JSON validation for all responses
• Azure CLI error capture and formatting
• Authentication error handling
• Parameter validation

Security Considerations

• Uses Service Principal authentication
• Supports environment variable configuration for sensitive data
• Implements proper error handling to prevent information disclosure
• Validates all input parameters
